The effects of finite word length in LMS adaptive noise canceller are discussed. The theoretical formula of output signal-to-noise ratio involving quantization noise and round-off noise are derived. If the variation of input weak signal can be reflected by certain word length, the output SNR mainly depends on the word length of adaptive operations.
